Temperature-regulating textiles take inspiration from polar bear fur

A thick coat of fur keeps polar bears warm in below-freezing temperatures, but did you know that the hairs on their pelts are hollow to provide extra insulation? Inspired by nature’s genius design, UK fashion brand HotSquash unveiled an innovative new clothing line that uses the same insulating qualities found in polar bear fur. The temperature-regulating textiles not only help retain warmth in cold climates, but are also engineered to wick away moisture on hot days and are very low maintenance.
